Ubuntu, a popular Linux distribution, is known for its robust command-line interface and versatile file system. There may be times when you need to list files in a directory without including subdirectories or their contents. This article will guide you on how to do just that using various commands.
To list files in a directory without subdirectories in Ubuntu, you can use the find command with the -maxdepth 1 option, or the ls command with the | grep -v / command. Additionally, you can use a Bash loop to achieve the same result.
Using the find Command
The find command is a powerful tool in Ubuntu, allowing you to search for files in a directory hierarchy. Here is how you can use it to list files in a directory without including subdirectories:
find . -maxdepth 1 -type f -printf '%f\n'Let’s break down this command:
.: This represents the current directory. You can replace this with the path of the directory you want to list files from.-maxdepth 1: This option ensures thatfindonly looks at the current directory and doesn’t delve into any subdirectories.-type f: This option tellsfindto only consider files, not directories.-printf '%f\n': This option formats the output to only display the file name (%f) and adds a newline (\n) after each file name.
Using the ls Command
The ls command is another common tool used to list directory contents. Here is how you can use it to list only files:
ls -p | grep -v /This command works as follows:
ls -p: This lists all files and directories in the current directory. The-poption adds a/at the end of each directory name.| grep -v /: This pipes (|) the output of thelscommand togrep, which filters out lines containing/, effectively removing directories from the list.
Using a Bash Loop
For more complex scenarios or scripting purposes, you might consider using a Bash loop. Here’s how:
for f in *; do [[ -f "$f" ]] && echo "$f"; doneIn this command:
for f in *: This iterates over all files and directories in the current directory.[[ -f "$f" ]]: This checks if each item is a file.&& echo "$f": If the item is a file, it gets printed out.done: This ends the loop.
Remember, replace * with the desired directory path if you want to list files in a specific directory.
Conclusion
Listing files in a directory without including subdirectories in Ubuntu can be achieved using various commands like find, ls, and Bash loops. Each of these methods has its own advantages and use-cases. Choose the one that suits your needs the best.
Remember to replace the current directory (.) with the desired directory path if you want to list files in a specific directory. Also, some of these commands may include hidden files. If you want to exclude hidden files, you can add the -a option to the ls command or modify the find command accordingly.

ls -p | grep -v /Yes, you can use a Bash loop to list only files in a directory without subdirectories. Here’s an example command:
for f in *; do [[ -f "$f" ]] && echo "$f"; doneTo exclude hidden files from the list, you can add the -a option to the ls command or modify the find command accordingly. For example, to exclude hidden files with ls, you can use:
ls -ap | grep -v /
